Description

Disc brakes, brake pads and brake pad sets for commercial vehicles

The present invention relates to a disc brake for a commercial vehicle according to the preamble of claim 1.

In a disc brake formed in the general type, in particular in the form of a sliding caliper brake, the actuating side brake pads are pressed against the vehicle side brake disc by an applicator which can be pneumatically or electrically motor operated during braking. In a further braking process, the brake caliper against the brake disc is displaced against the application direction of the operating side brake pads onto the other side of the brake disc under the action and pressure of the reaction side brake pads located on the opposite side.

For the prior art, DE 40 20 287 A1 is first mentioned. According to this document, a pad spring formed of a leaf spring is provided on each of two brake pads. The pad carrier is retained by a pad spring, respectively, after being introduced into the pad shaft, and the pad spring is held in a laterally extending manner relative to the longitudinal axis of the leaf spring, It is fixed through a bar. For securing the pad spring, a tab provided with an undercut is molded on the pad carrier (or pad carrier plate), the tab passing through the slot-shaped recess in the pad spring, In combination, a shape fitting lock is formed, through which the pad spring is retained in the radial direction and the automatic separation in the relaxed or partially relaxed position is blocked. A further similar prior art is shown in DE 14 2014 106 090 A1. According to this document, brake calipers each have a central caliper opening on the brake disk, through which two brake pads can be inserted into the pad shaft, which enables simple replacement of the brake pads. On the other hand, this is necessary. The brake pads are fixed radially (toward the outside with respect to the brake disc rotation axis within the scope of the present application) in a simple manner into the pad shaft.

This problem with fixed caliper brakes is not given in this form because the strut is guided through the brake disc, which may include ventilation openings, but whose dimensions have not been considered and determined for pad replacement . Thus, a hold down bar extending through the caliper opening is not required.

The solutions described in the introduction are respectively improved in the patent EP 1 963 702 B1 and EP 2 255 101 B1. According to this solution, the pad spring can be fixed to the pad carrier, preferably in the radial direction thereof, by the hood penetrating by portions or portions of the pad spring, As shown in Fig.

The technical background is further described in EP 0 694 134 B1, DE 10 2012 110 461 A1 and WO 2014/079 869 A1.

An object of the present invention is to improve the general type of disc brakes so that good braking behavior is achieved by means of structurally simple means. A further challenge is to provide a corresponding brake pad and a corresponding set of brake pads.

This problem is achieved through a disc brake having the features of claim 1. A further proposed task is achieved through a set of brake pads having the features of claim 22. The above object is also achieved by the method of claim 26.

Claim 1 is a brake caliper formed on both sides of a brake disc, preferably in the form of a sliding caliper, disposed on a position-fixed brake carrier and having an applicator for actuating the brake A brake caliper, two brake pads each comprising a pad carrier and a friction pad secured thereon, one of the two brake pads being connected to a brake disc on one side of the brake disc by an applicator as an acting side brake pad And the other one of the two brake pads is disposed on a side positioned opposite to the brake disc as a reaction side brake pad and each of the two brake pads is inserted into the pad shaft of the brake carrier, Wherein the brake caliper A brake disc for a commercial vehicle, comprising a central caliper opening over a brake disc, through which two brake pads can be inserted into respective pad shafts of the brake carrier, A hold down bar is provided which is configured to radially lock only the brake pads in the pad shaft within the brake carrier and the hold down bar is retained on the brake caliper by its end directed away from the brake pads, Wherein the brake pad is fixed within the pad shaft in the brake carrier radially in a form-fitting locking fashion.

On the one hand, in this way, there is provided an associated hold-down bar, including advantageous disc brakes and particularly advantageous reaction side brake pads, and a limited structural form for the function of the hold down of the radial brake pads in a simple and short and advantageous manner. The short hold down bar causes a reduction in weight of the brake and a reduction in cost through the injection of a small amount of material. This is complemented by advantageously placing the working side brake pads on the pad shaft within the brake carrier, where it is simply radially fixed through the shape fitting lock (particularly through the lateral projection). The two brake pads are fixed in this manner simply and preferably radially differently to the brake carrier, whereby the overall disc brake is advantageously improved and optimized. The working side brake pads additionally reduce the effect of the slope wear through its design.

According to an advantageous improvement, the working-side brake pads comprise a pad spring, which is held or fixed on the working-side brake pads (preferably in the central region), and the brake carrier horn of the brake carrier ), The working side brake pads are preferably pulled radially upwardly within the pad shaft within the brake carrier. In this way, the working side brake pads are pulled radially outwardly (away from the brake disk rotation axis) in the pad shaft through the pad spring, so that the working side brake pads are positioned in the pad shaft particularly well and reliably do.

According to the present invention, there is also provided an advantageous and simple method for mounting a brake pad in a disc brake according to any one of the related claims,

a) the reaction side brake pads are radially inserted into the pad shaft in the brake carrier, wherein the reaction side brake pads are then fixed radially by a hold down bar disposed on the brake caliper , step,

b) the working side brake pads are first introduced or inserted into the disc brake radially and then moved to a position in the pad shaft which is assigned to the working side brake pads in the brake carrier via axial movement, Position, the working side brake pads are fixed radially between the working side brake pads and the brake carrier through the shape fitting lock, and

c) arranging the ends of the pad spring held on the working side brake pads on the brake carrier horn of the brake carrier such that the ends are resiliently positioned on the brake carrier horn of the brake carrier

.

In particular, the mounting of the action side brake pads is very simple in this way. Each of the two brake pads is simply and reliably mounted in the pad shaft.

It is advantageous for the hold down bar to only axially extend and circumferentially surround one of the two brake pads in a direction parallel to the brake disk, either completely or partially. In this manner, the pad is held in the pad shaft of the brake carrier or the pad shaft of the brake carrier from the " top " brake in a generally radial direction and is secured against movement (too large a radial direction). In this case, the reaction side brake pad, which is fixed radially or hold down, can be inserted into the pad shaft of the brake carrier. Two brake pads are disposed in the pad shaft of the brake carrier and can be inserted into the pad shaft through openings in the brake caliper (the openings are mounting openings for the brake pads) It is a particularly preferred embodiment to be able to be inserted in a complementary manner through a smaller axial movement. A brake carrier having a pad shaft on two sides of the brake disc is very stable and advantageous. The pad shaft supports the pad circumferentially and radially downwardly against the brake disc. In this case, the "short" hold down bar in the axial direction fixes the brake pads upward against the fall and too large radial movements, possibly supported by the spring disposed therebetween. The other brake pads are fixed radially in another advantageous way (not by the same hold down bar).

The locking of the reaction side brake pads by the " short " hold-down bars is particularly advantageous when the brake pads are kept from moving axially in the brake caliper and are not displaced, in particular in the region of the back plate or pad carrier plate, It can be easily implemented.

In this case, it may be detachably or non-detachably fixed on the brake caliper according to a variant of the hold down bar, or it may be designed integral with the brake caliper.

An alternative embodiment of a hold down bar with such a brake pad as an assembly that is replaced as a whole during pad replacement is advantageous. This is straightforward and leads to a simple and reliable update of all elements to be replaced on the " reaction pad " assembly (brake pads, pad springs, if present: hood and hold down bar).

The hold down bar can be supported on the pad carrier or engage behind the pad carrier and interact with the pad carrier in this manner. The hold down bar may also interact with the pad carrier in a form-fitting locking manner, for example, to fit into the area of the corresponding groove in the pad carrier in a form-fitting locking manner (or vice versa).

As a possible (particularly advantageous) variant, the hold-down bar can be connected to the pad in such a way that it can not be lost, and in particular can be connected to the pad carrier so as not to be lost. This has the advantage that such an assembly is completely installed and therefore eliminates installation errors. The installation error means in this case that the back plate is installed toward the brake disk.

In this case, different types of connections between the hold down bar and the brake pads are possible. The connection may be through the hood, in which case one or a plurality of tabs are provided which completely or partially surround the hold-down bar and then mounted by welding, riveting, tumbling or the like, It is no longer possible. Surrounding can be made toward the rear or upward as shown in the figure.

The connection can also be made through a collar bolt, which is, for example, penetrating through a hold down bar and welded or riveted onto the hood (material-engaging, friction-locking or shape-fitting locking).

The connection can also be made through bolts, which are fixed or fixed to be displaceable within the pad back plate.

The hold down bar may also completely or partially penetrate the pad back plate. Then, in this variant, the spring is permanently fixed on the hold down bar so that the hold down bar is connected to the pad so that it can not be lost (as already mentioned above).

In another concept, the pad retention spring may be displaced away from the pad. In regions spaced from the pad, generally low temperatures occur directly on the pad, which also positively affects not only the life but also the greater selectivity of the spring material. Since the spring is protected by the coating against corrosion, the temperature likewise acts on its lifetime, where improvements can also be made. Here, the hold down bar is fixed with the pad or connected with a clearance for tolerance compensation. The spring in this case presses the hold down bar downward. Above the hold down bar, the pad is urged downward on the brake carrier. Such a spring may be achieved through different spring embodiments, such as, for example, leaf springs, helical springs, leg springs, and the like.

The holding or holding of the hold down bar on the pad and / or the brake caliper can be accomplished simply by one or more fastening means, in particular by bolt (s) or clip (s) or one or more screws (s).

Thus, the case where the hold down bar is not releasably secured on a portion of the reaction side brake pads can be considered and is advantageously simple. For example, it may be fixed on the pad carrier in a material-binding manner, such as, for example, welding.

The present invention also provides an advantageous brake pad for a disc brake according to any one of the related claims, the brake pad comprising a pad carrier in which the brake pad is configured to interact with the hold down bar and a friction pad fixed thereon do. Where the hold down bar and brake pads may (but need not) form an assembly.

In this case, the hold down bar is formed in such a manner that only the reaction side brake pads are fixed radially with respect to the disc brake in the pad shaft.

In this case it is particularly advantageous that the hold down bar is fixed on the reaction side brake pads because the hold down bar is axially fixed within the brake caliper and is not displaced in the brake caliper as wear increases. In this regard, the present invention can be implemented simply here. However, the present invention is not limited to these variations.

According to another advantageous variant, there is provided a cable bridge in which at least one signal cable is arranged and maintained, the cable bridge bridging the opening of the brake caliper and directly or indirectly in at least two areas, Respectively. In this way, the signal cable can be well placed through the opening of the brake caliper despite the " short " hold down bar.

There is also provided a set of brake pads having reaction side brake pads and reaction side brake pads according to any one of claims 22 to 27 having reaction side brake pads, wherein the working side brake pads have at least one shape And a pad spring fixed on the working side brake pad and fixed on the pad carrier in a radial direction within the brake carrier by a custom locking element, the pad spring being resiliently positioned on the brake carrier horn of the brake carrier Wherein the reaction side brake pads are configured to interact with the hold down bar and wherein the hold down bar is configured to radially fix only one of the two brake pads in the pad shaft relative to the disc brake .

In this way, the operating side brake pads do not require a hold down bar for radial locking on the working side. In addition, such pads reduce the tapered wear effect. In accordance with the teachings of the present invention, the reaction side pad also need not necessarily include this structural form. Rather, it can be designed without protrusions. Thus, a " short " hold-down bar is particularly advantageous. Overall, a very cost effective disk brake with two brake pads optimized for this task is provided as a set of pads.

Briefly, as a brake caliper formed over both sides of the brake disk, preferably in the form of a sliding caliper, is fixed on a position-fixed brake carrier and includes a central caliper opening on the brake disk, A disc brake for a commercial vehicle is also advantageously provided, comprising a brake caliper, wherein the disc brake comprises a caliper opening, each comprising a pad carrier and a friction pad secured thereon, Wherein one of the two brake pads can be pressed against the brake disc on one side of the brake disc by an applicator as an acting side brake pad and the other of the two brake pads One is the reaction side break A brake arranged on the side which is located at the other side of the disc, two brake pads, one is fixed to only one in the radial direction in the pad shaft or provided, holddown bar is formed so as to be radially hold-down for the brake disk axis of rotation.

The present invention also relates to an improved version of the above-mentioned variant and to a disc brake having an advantageous brake carrier (claim 14) in an embodiment which can be regarded as the invention itself. A typical type of brake carrier for a disc brake of a commercial vehicle which can be operated pneumatically or electrically motor-operated is used to fix substantially on the vehicle axle, for example, by screwing on an axial flange of such a vehicle shaft A connecting region and a pad shaft for receiving and supporting at least one brake pad. In this case, the pad shaft is formed through and from such protruding carrier horns with bearing surfaces for radial support of the brake pads, the carrier horns guide the respective brake pads in the lateral direction, And receives braking force transmitted by the disc onto the brake pads. Brake carriers that span both sides of the brake disc are also known to have two pad shafts for receiving the working side brake pads and the reaction side brake pads. In this case, a brake pad directly moved or driven by the application unit of the disc brake is defined as an operation side brake pad. The pad of the second brake, which is pressed onto the reaction side friction surface of the brake disk through the movement of the brake caliper after pressing of the working side brake pads onto the brake disk, is also defined here as the reaction side brake pad.

To mount the brake pads into such a pad shaft of the brake carrier, the brake pads are introduced radially into the rotational axis of the brake disc along the inner surface of the carrier horn and into the pad shaft of the brake carrier. When the inner surface of the carrier horn is formed flat and the geometry of the pad shaft is substantially rectangular, it is introduced through the pad shaft opening of the brake caliper of the disc brake very simply into the pad shaft directly from above .

However, this arrangement can be used, for example, in the form of a hold down bar extending upwardly in the direction of the axis of rotation of the brake disc relative to the pad shaft opening of the brake caliper, in particular for fixing the brake pad in the radial direction, , Additional holding or locking systems of pads or brake pads.

In the case of a brake carrier designed such that the carrier horn is so shaped and locked in a radial manner on one or two of the respective carrier horns, one or two brake pads on each side of the brake pad, After each first radial movement through the opening of the brake caliper, each of the brake pads is first moved axially parallel to the vehicle axis in the pad shaft until the corresponding recesses on the inner side of the carrier horn of the carrier overlap, , It is necessary that the brake pad reaches the insertion position and at this insertion position the brake pad can then be inserted into the pad shaft in the direction of the rotation axis of the brake disk. Such a brake carrier is known, for example, from DE 10 2015 114 351 A1.

It is desirable to be able to perform positioning as quickly and simply as possible in the assembling process, particularly at the time of mounting the operation side brake pads covered by the disc brakes.

In this respect, the improvement of the above-discussed variant and also the problem of the individual invention is to provide a disc brake with a brake carrier in which the mounting of the brake pads is simplified.

The above object is achieved by a disc brake having a brake carrier having the features of claim 14.

Accordingly, a brake carrier for a pneumatic or electric motor-actuated disc brake of a commercial vehicle includes a connection area for securing on the vehicle axle, and at least one pad for receiving and supporting at least one brake pad Shaft.

The pad shaft is formed by an inlet side carrier horn, an outlet side carrier horn, and a bridge connecting the inlet side carrier horn and the outlet side carrier horn. In this case, the areas of the bridge adjacent to the carrier horns form bearing surfaces for radial support of the brake pads.

On the sides of the carrier horns are arranged guide contours for guiding the brake pads individually from the side of the pad shaft into the insertion position, and the brake pads at the guide contour are axially spaced from the carrier horns Can be inserted into the shaft.

This type of brake carrier allows for easy alignment of the brake pads which can be introduced into the pad shaft of the brake carrier, because positioning in the correct center position of the brake pads is forced through the guide contour.

When the brake pads are initially set to be laterally displaced upon radial insertion, the side edges of the pad carrier plate of the brake pads contact the guide contour and are guided along the guide contour to the correct insertion position.

Advantageous variants of the invention are the subject of the dependent claims.

According to an advantageous variant embodiment of the brake carrier according to the invention, the bearing surfaces for the radial support of the at least one brake pad are arranged in the mounting area, in order to limit the sliding movement of the brake pads from the side of the pad shaft into the insertion position, As shown in Fig. This enables insertion of the brake pads into the insertion position in a simple manner, in which case the brake pads can be displaced in the pad shaft in parallel to the rotational axis of the brake disc.

According to a preferred variant of the invention, the guide contours are molded on the sides of the carrier horns as the material expansion of the carrier horns. The guide contours can be molded on the carrier horn during the casting process of the brake carrier in a simple manner.

In this case, the guide contours are preferably formed to be narrower toward the bridge.

Particularly preferably, each of the guide contours has at least one straight guide area, and the straight guide area allows each brake pad to be guided to a precise center position in positioning the first lateral displacement do.

In the case of a brake carrier in which on the inner side of each of the carrier horns a protrusion acting to radially fix the brake pads by means of a correspondingly formed pad carrier plate with lateral recesses is formed, Each receptacle is molded under the projection for receiving each projection, and the guide contours are each terminated on the respective side edges of the respective receptacle.

Through this, the brake pads can always be guided to the correct insertion position along one of the guide contours.

The disc brake according to the present invention includes a brake caliper which can be displaced on both sides of the brake disc and on both sides of the brake disc a brake pad arranged on the pad shaft of the brake carrier is fixed to the pad carrier plate and the pad carrier And has a friction pad fixed on the plate.

The brake pads are held on the carrier horn of the brake carrier in a form locking fashion in the radial direction with respect to the rotation axis of the brake disc at the entrance side and the exit side, and the brake carrier is formed as described above.

Preferably, only the working side carrier horn includes a guide contour for guiding the brake pads into the insertion position laterally of the brake pads.

In particular, when mounting the working side brake pads, the precise alignment in the normal case becomes difficult through interference with the view through the brake discs, so that the guide contour proposed herein makes the mounting obviously easier.

Another advantageous embodiment of the invention is characterized in the dependent claims.

Figures 1a, 2, 9 and 10 show a disc brake for a commercial vehicle, respectively. The disc brake includes a brake caliper (1) that spans both sides of the brake disc (2). Relevant electrical or pneumatic actuators (e.g., brake cylinders) are not shown. The brake disk (2) includes a brake disk rotation axis (D). The brake caliper 1 is disposed on the brake carrier 3. Herein, the brake caliper 1 is arranged in the direction of the brake disc rotation axis D with respect to the brake disc 2 in the preferred embodiment (the concepts such as "axial direction" and "radial direction" And is disposed on the brake carrier 3 so as to be displaced in the axial direction. Further, the brake caliper 1 is mounted on a guide rail 4 which can not be recognized in detail here, and the guide rail is connected to the brake carrier 3 held in the vehicle in a position fixed manner.

The brake caliper 1 includes a working section 1a, a caliper back plate 1b and two tension struts 1c. The working section 1a accommodates an unillustrated applicator of the disc brake 1.

The working section 1a extends on one side of the brake disk 2 with one side parallel to the plane of the brake disk 2. On the other side of the brake disk 2, the caliper back plate 1b is arranged so as to extend parallel to the brake disk 2 as well. The caliper back plate 1b is connected to the working section 1a on each end with a respective tensile strut 1c. In this case, the tension strut 1c extends substantially perpendicular to the working section 1a and the caliper back plate 1b.

In this arrangement, the working section 1a, the caliper back plate 1b and the tension strut 1c are positioned such that they have a central opening 1d extending therebetween so as to span both sides of the brake disk 2. [ The opening 1d comprises an imaginary longitudinal centerline, which lies in the plane of the brake disc 2 and connects the imaginary center of the tension strut 1c. The opening 1d also includes another imaginary transverse centerline, which connects the imaginary center of the working section 1a with the imaginary center of the caliper backplate 1b.

Brake pads 100 and 200 are provided on both sides of the brake disc 2 (not shown in Fig. 9). A brake pad 100 (hereinafter also referred to as an action side brake pad 100) is disposed on the side of the application apparatus. Another brake pad 200 (hereinafter also referred to as a reaction side brake pad 200) is disposed on the side opposite to the operation side of the brake disk 2.

The central caliper opening 1d on the brake disk is designed or dimensioned so that two brake pads can be inserted into the brake carrier through the caliper openings, which allows simple pad replacement.

The braking is effected by an application device having a brake lever which is arranged in the receiving space at a position in the application area 1a of the brake caliper 1 and the brake lever is connected to the dome or working section 1a of the brake caliper 1 . The applicator is actuated by an actuator not shown. The applicator is preferably operated pneumatically or electromechanically. To this end, a brake cylinder is preferably provided (not shown here) which can be placed on the brake caliper of the disc brake.

The two brake pads 100, 200 can be pressed on both sides with respect to the brake disc 2 during braking. The working side brake pads 100, when designed as sliding caliper brakes, are in contact with the brake disk 2 during braking. In the next process, due to the reaction force generated, the brake caliper 1 is displaced synchronously with the reaction-side brake pad 200 in the opposite direction until the brake caliper 1 is similarly brought into contact on the brake disk 2 in a frictional manner .

Each of the brake pads 100 and 200 (see Figs. 3, 4 and 11 and 16) includes friction pads 110 and 210 and friction pads (not shown) fixed on the side facing the brake disc 2 120, 220, which are pressed against the brake disc 2 during functioning, i.e. braking.

The brake pads 100, 200 can be reached through a central opening 1d for exchange and for maintenance. The brake pads can be inserted into and removed from the associated pad shaft radially from " above " through this central opening 1d. The terms " upper " and " lower " are used below in this sense.

The working side pad shaft 11 for the working side brake pads 100 is formed on the brake carrier 3 on the side of the application device or on the working side section of the brake carrier. This can be seen in FIG.

It is expected that the brake carrier 3 surrounds the upper edge region of the brake disk 2 in the form of a frame and has an action side and a reaction side section. In this case, preferably, a second pad shaft 12 for the reaction side brake pads is also formed in the brake carrier 3 (see Figs. 1A and 1B on the reaction side). However, alternatively, the reaction side pad shaft 12 for the reaction side brake pad 100 may be formed in the brake caliper 1 (the brake carrier includes only one operation side section, Section, not shown here).

The pad shafts 11, 12 (see Figs. 1A and 1B) each have brake carrier horns 13, 14 and 15 (see Figs. 1A and 1B) laterally (or in the rotational direction U and in the opposite direction of the rotational direction U) 12c defined by the support surfaces 11a, 11b, 12a, 12b defined by the brake carrier horns 13, 14 or 15 and 16, respectively, .

The working side brake pads 100 and the reaction side brake pads 200 are formed differently here. In this case, the working side brake pads 100 can be formed again in various ways. 2 and 3 are particularly advantageous in this respect, but are not compulsory.

The working side brake pads 100 (suitable for the brakes of Figs. 1 and 9) of Figs. 2 and 3 include a brake carrier 110 and friction pads 120 disposed on one side of the brake carrier 110, This friction pad is directed to the brake disk 2 in the installed state. The pad carrier 110 again includes two side edges 111, 112 parallel to the associated bearing surfaces of the brake carrier horns 13, For the preferred direction of rotation U (corresponding to the front running), the side edge 111 is formed on the outlet side and acts as a bearing surface during braking from the front running direction. For the preferred direction of rotation U (corresponding to forward running), additional side edges 112 are formed at the entry side. They act as a bearing surface during braking from the rear running direction.

At least one protrusion 113, 114 protrudes outwardly in opposite directions on each of the side edges 111, 112 (here, on the lower edge in the pad shaft 11). Each of these projections 113 and 114 is engaged with corresponding undercuts 17 and 18 of the brake carrier 3 respectively formed in the brake carrier 3 of the working side pad shaft 11 ). The working side brake pads 100 installed in this manner are fixed to the brake carrier 3 in the radial direction and are prevented from rotating during braking. The protrusions also serve as additional support areas during braking. At the time of replacement, a new brake pad 100 is inserted radially, in which case the projections 113 and 114 are axially displaced to engage the undercuts 17,18. The undercuts 17 and 18 are preferably formed on the support surfaces of the carrier horns of the two circumferentially positioned brake carriers 3. [

The working side brake pad 100 may also include a pad spring 130. The pad spring is fixed to the action-side brake pads. This is implemented here as follows: The pad spring 130 is coupled to the center of the pad carrier 110 or below the retaining bar 115, which is integrally formed with the pad carrier. The pad spring 130 is secured in this manner in the radial direction. The pad spring 130 also has slots 131 and 132 on opposite sides of the retaining bar and the slots are penetrated at the upper side of the pad carrier 110 by the tabs / protrusions 116 and 117 . In this manner, the pad spring 130 is prevented from rotating about its axis. The ends 133, 134 of the pad spring 130 are preferably resiliently positioned on the brake carrier horns 13, 14. In this way, the working side brake pads 100 are pulled upward from the pad shaft 11 of the brake carrier 3 through the spring bias. In this way, the working side brake pads 100 in the brake carrier 3 are preferably held fixed particularly in the radial direction. Therefore, a hold down bar fixed to the brake caliper is not required. Also, jolting is very well prevented by the spring.

The reaction side brake pads 200 of Figures 4 or 11 again include a pad carrier 210 and a friction pad 220 that is integrally disposed thereon and which faces the brake disc 2 in the installed state .

The pad carrier 210 is again in parallel alignment here and additionally has associated bearing surfaces 12a and 12b of the brake carrier horns 15 and 16 of the reaction side pad shaft 12 of the brake carrier 3 And two side edges 211, 212 that are positioned parallel to each other.

For the preferred direction of rotation U (corresponding to the forward drive), the side edge 211 is again formed on the outlet side and in this way serves as the bearing surface during braking from the forward running direction. For the preferred direction of rotation U (corresponding to forward running), the other side edge 212 is again formed on the entry side. The side edges serve primarily as bearing surfaces in this manner during braking from the rear running direction.

The reaction side brake pads 200 (see FIGS. 4 and 5 and 12, 13 and 15) include a pad spring 230. At the upper longitudinal edge of the pad carrier 210, the pad retention spring 230 is preferably detachable from the hood 240 (see Figures 5, 6, 8, 12, 13 and 15) Fixed or placed / maintained. Preferably, the hood 240 is deflectably restrained against the pad carrier 210.

(Here, on the lower edge of the pad shaft 12) of the pad carrier 210, in which case the projections do not protrude outward in directions opposite to each other. Therefore, these brake pads are not fixed in this manner in the radial direction. Therefore, another device for radial fixation in the pad shaft is needed. In order to fix the reaction side brake pad 200 to the pad shaft 12 in the radial direction, a hold down bar 250 is provided (in this regard). The hold down bar may be designed as a single part or as a plurality of parts.

The hold down bar 250 is fixed on the brake caliper 1 at one end 251 and is not separated from the brake caliper 1 during braking. However, it can be removed from the brake caliper 1 for pad exchange.

The hold down bar 250 is designed and formed to hold down only one of the two brake pads 100, 200. Here, while the hold down bar holds down the reaction side brake pad 200, it is the action side brake pad 100 that the hold down bar does not fix or hold down in the radial direction.

The hold down bar 250 is preferably a substantially flat component perpendicular to the axial direction. This is advantageous, but not necessary. However, space - saving design is possible. The cross-section of the hold down bar 250 may preferably be a rectangle having two parallel short sides and two parallel long sides.

In this way, these hold down bars 250 interact with the brake pads 200. The brake pad 200 is designed to be held down either directly by the hold down bar 250 or through one or more inserted elements. The brake pads extend from the brake caliper back plate 1b into the caliper opening 1d in parallel to the brake disk axis and the brake pads protrude into the caliper opening but do not completely bridge. The opposite end 252 of the brake caliper 1 extends over the pad carrier 210 of the reaction side brake pad 200. However, this end 252 preferably does not extend over the brake disc 2, and more preferably does not extend over the working brake pad 100 (see FIGS. 1 and 9).

Further, the caliper opening 1d also does not extend upwardly in the axial direction (parallel to the brake disk). Thus, this hold down bar 250 is structurally simple yet nonetheless very secure. The hold down bar should be fixed only on the brake caliper 1, preferably only on the edge of the opening 1d on the caliper back plate 1b.

The end 252 of the hold down bar 250 opposite the brake caliper 1 extends at least over the pad carrier 210 of the reaction side brake pad 200. [ It also preferably extends from the brake caliper 1 over the hood 240 through which the pad spring 230 or a portion of the pad spring 230 extends in the axial direction.

According to one variant, it is advantageous if the hold down bar 250 extends only axially over the reaction side brake pads 200 and is secured in this manner in the radial direction, but not on the brake pads 200 . In this way, good radial fixation of the reaction side brake pads 200 is achieved.

According to another variant, it is also advantageous when the hold down bar 250 is also fixed on the reaction side brake pad 200 as well. In this way, a mounting unit which can be handled simply is formed, which facilitates pad exchange.

According to an improvement of this modification, it is advantageous that the hold-down bar 250 is not detachably fixed on the reaction side brake pad 200.

In this way, a mounting unit which can be handled simply on the one hand is formed, and on the other hand, the hold down bar 250 (which is strongly loaded due to the many brakes) is securely replaced when the pad is replaced .

For separation, only the fixing of the hold down bar 250 on the brake caliper 1 is released. The reaction side brake pads 200 are then exchanged with the hold down bar 250 as an assembly. Preferably, such an assembly also advantageously includes a pad spring 230. More preferably, such an assembly advantageously includes hood 240 as well.

Down bracket 250 to the reaction side brake pads 200 may be accomplished in various manners through connection of a shape locking system or a material coupling system with a part of the reaction side brake pads 200. [ As such a portion, according to a variant (see FIG. 16), the pad carrier 210 fits or the pad spring 230 fits (not shown). And as such, if present, the hood 240 is also suitable. These advantageous modifications have been implemented in the drawings of Figs.

The hold down bar 250 may be connected to the hood 240 in a material combination manner and may be welded or brazed, for example directly or indirectly (via intermediate parts such as bolts). The hold down bar 250 can be screwed to the hood 240 or can be riveted to the hood 240 (not shown).

Alternatively, it may be desirable if the hood 240 comprises an integrally molded part such as an arm or a plurality of arms or even a circumferentially closed ring 245 (Figure 6) Down bar 250 is connected to the hood 240 in a detachable manner. Ring 245 is preferably penetrated by hold down bar 250 (Figure 4). In addition, the hold down bar 250 may be welded to the ring 245, for example, in a material bonded manner.

In the side view (e.g., see FIG. 4), the hold down bar 250 may be formed in a stepped shape. This serves in particular to compensate for the height offset to brake caliper 1. This Z-shape may also be used for simple, uncomplicated fixing of the hold down bar 250 on the brake caliper 1. [

One end of the hold down bar 250, which is fixed on the brake caliper 1, can be secured thereto in various ways. Advantageously, such an end is fixed in a form-fitting locking manner by the pin 255 on the brake caliper 1 (Figs. 1A and 9). The pin 255 also passes through the bore-like opening 1e here and on the hold down bar 250 at two spaced apart tabs 1f on the brake caliper 1, The end 251 is positioned on the brake caliper 1 between the taps 1f. Here, the T-shaped configuration of the end 251 ensures that the hold down bar 250 can not slide axially through the tabs 1f.

The two ends of the pad retention spring 230 (see FIG. 4 again) are provided with slots or protrusions 213, 214 formed on the pad carrier 210, (231, 232) are provided.

As can also be seen particularly in FIGS. 4 and 15, for a non-separable, unsuitable connection of the pad retaining spring 230 and the pad carrier 210, a hood, preferably having a transverse cross- 240 are provided with two parallel legs 244 connected to one another via a web 243 at the top of the pad carrier 210 and another web 244 (through the opening of the pad carrier 210) 241, 242 are provided.

A longitudinal slot 233 is provided in the pad retention spring 230 midway between approximately the slots 231 and 232 and one of the legs 242 of the hood 240 is inserted through the longitudinal slot, Legs 241, which are located on one side of the legs as well as on the opposite side, are also adjacent or near the assigned width side of the pad carrier 210.

5, the pad retention spring 230 is preferably wider or thicker than the axial thickness of the pad carrier 210, so that the pad retention spring 230 is positioned between the friction pad 220, And the other longitudinal edge is substantially aligned with the rear side of the pad carrier 210. [ It can also be seen in FIG. 5 that adjacent legs 241 under a connecting web 244 extending parallel to the web 243.

Through the preferred material-bonded connection, the non-destructive separation of the hood 240 is eliminated, thereby ensuring secure fixation of the pad retaining spring 230. The hood 240 may also be secured to the pad retention spring 230 or the pad carrier 210 in a material coupled manner.

The legs 241 and 242 are preferably designed in a trapezoidal shape in a plan view thereof and are displaceable through the through hole 215 in the pad carrier 210 while the wide side is formed by the web 243. [ The connecting web 244 defining the narrow side. As already mentioned, the longitudinal slot 233, which is based on the longitudinal extension of the pad retention spring 230, is preferably disposed substantially centrally. Most particularly preferably exactly in the middle (see also patent EP 1 963 702 B1 and EP 2 255 101 B1 for background art).

Preferably, the hood 240 is deflectably restrained radially on the pad carrier 210. To this end, the hood 240 passes through the through hole 215 by the web 244.

Since the reaction side brake pads 200 do not change their positions in the brake caliper 1 as the wear increases, the reaction side brake pads 200 together with the reaction side brake pads 200 form the hold down bar 250 directly as an assembly It is possible. To this end, the hood 240, which extends in this way (as in Figures 4, 11 and 5 and 12) for another previously unknown function (hold down bar fixing) is particularly suitable. In this way, particularly advantageous reaction side brake pads (not shown) which include a hold down bar 250, which preferably comprises a short and advantageously limited structural form, for the function of the hold down of this one brake pad 200 are provided. To mention this, it is also simple installation, reduced manufacturing cost, low load and ensuring accurate installation.

Thus, the design of the hold down bar 250 with such a brake pad as an assembly that is totally replaced when the pad is replaced is advantageous. This is simple and updates all elements to be changed on the " reaction pad " assembly (brake pad, pad spring, if present: hood and hold down bar).

According to Figures 2-8, the hold down bar 250 preferably also passes through the ring 245 of the hood 240, which is fixed in a material coupling manner, but according to Figures 9-15, the pin 254 Down bolts 250 on the hood 240 to thereby secure the hold down bar 250 on the brake pads 200. The brake pedal 200 may also be used to lock the hold down bar 250 on the hood 240. [ The pin 254 passes radially through the hold down bar in the region of the bore 253 (Fig. 14) and is welded to the hood 240, for example, or is otherwise welded thereto (e.g., Etc.). The ring 245 may be formed of a tab of the hood 240 and may be formed in a manner that is closed in the circumferential direction or not closed in the circumferential direction.

The hold down bar 250 may also be disposed on the pad spring 230 or directly on the pad carrier 210 (the latter variation is illustratively shown in FIG. 16).

The pad carrier 210 includes an end 252 of the hold down bar 250 facing the pad carrier 210 according to Figure 16 which also means " a section located proximate to the pad carrier 210 " Includes an opening (216) that engages. The openings 216 may be designed as clogged holes or through openings. The other end portion 251 of the hold down bar 250 (or an area positioned closer to the brake caliper 1) is formed on the opening 1d / within the opening (preferably not releasable) And / or a material bonded manner. The end portion 251 of the hold down bar 250 located close to the brake caliper 1 is directed toward the brake caliper 1 and there (preferably detachably) engages with a shape locking system and / (Here, in a manner not shown, for example, similar to Fig. 1A or 17). In addition, a spring 256, which may be used for the elastic support of such a brake pad 210 relative to a contact such as the brake caliper 1, may be provided on the hold down bar 250 Not shown in FIG.

The hold down bar 250 can pass completely or partially through the pad back plate or pad carrier 210 in this manner. The spring 256 is then fixed on the hold down bar. In this manner, the hold down bar (as already mentioned above) together with the spring 256 is inadvertently connected to the reaction side brake pad 200. The pad retaining spring is displaced or axially spaced from the brake pad 200 in this manner. This provides the advantage described in the introduction to this.

According to Figures 17A, 17B, 17C and 17D, the hold-down bar 250 preferably includes an end 251 of the hold down bar 250, which is fixed on the brake caliper 1, (E.g., bore) parallel to the brake disc 2, such that it is held by a bolt or pin 255 extending parallel to the plane of the brake disc 2. [ The bolt or pin 255 also passes through the through hole 257 and the tabs 1f on the brake caliper 1. [ The bolt or pin 255 has a head 255a on the outside of the two tabs 1f on one end and is fixed with the fixing element 260 (here a washer and splint) on the other end. Shaped locking means such as protrusions 258 under the hold down bar on the other end 252 of the hold down bar on the pad carrier 210 or the pad spring 230 may be formed on the pad carrier 210, The brake pads are fixed axially and radially, because they interact with locking means in a form-fitting locking manner. The end 251 of the hold down bar 250 which is fixed on the brake caliper 1 is also provided with a recess 1g of the brake caliper 1 which further secures the hold down bar 250 on the brake caliper in the axial direction ).

The outline 2502 of the end portion 251 of the hold down bar 250 on the brake caliper 1 preferably prevents the rotation of the hold down bar 250 not connected to the brake pad 200 And ensures compliance of the brakes with a predetermined envelope contour. In the variant described above, this is likewise embodied via the end 251 of the hold-down bar 250 on the brake caliper 1. Another outline 2501 (downward protrusion) on the hold down bar inserted in the recess 1g is formed in the bottom of the hold down bar 250 which is to be pressed against the pad spring 230 to introduce the bolt 255 Thereby facilitating mounting.

According to Fig. 18, the hold down bar 250 is detachably mounted on the brake caliper 1 on the brake caliper 1 in a simple manner by one or more screws 259 threaded in, for example, radially here, It is fixed as much as possible.

One through opening 257 or a plurality of through openings 257 for the bolt or pin 255 for fixing or holding the hold down bar 250 may include a circular cross section or other angled cross section (Figs. 19A and 19B; Figs. 20A and 20B). The pin may be matched to it and may have the shape of a circular pin or a flat bridge (not shown here, but may also be curved at one end or may include an angled portion or an enlarged head, So that it can come into contact with the opening and slip through it). On the other side of the through opening, by a splint or nut on the threaded section or by other suitable means. The pins 255 in the form of flat bridges are configured to engage one or more corresponding through apertures (s) of the tabs or tabs 1f on the brake caliper 1 and one or more through apertures (s) 257 of the hold- Lt; / RTI > In this manner, rotational fixation for hold down bar 250 is also implemented.

The hold down bar 250 may be manufactured in a variety of ways. This can be done by stamping / curving parts (e.g., as flat flat bridges supported on brake pads 200 with two tabs 261) or as shown in Figure 20a (which is supported vertically on brake pads 200) As a flat bridge) or may be formed of, for example, molded parts or other manufactured parts.

The exemplary embodiments of Figures 21A, 21B and 22A-22C will be observed in greater detail below.

A wear sensor (not shown) is incorporated into each of these for the purpose of detecting wear of the brake pad or friction pad 220 caused by braking. A signal cable (not shown here) is connected to each of the wear sensors. It comprises at least one conductor, preferably at least one conductor. The at least one conductor may be surrounded by an insulator and / or a cable sheath.

At least one signal cable is arranged to completely traverse the opening 1d of the brake caliper 1 and is guided to the brake pad wear detection device (not shown here) and possibly to the display device of the disc brake. To this end, the signal cable is placed and held on the cable bridge 271. The cable bridge 271 completely traverses or traverses the opening 1d of the brake caliper 1.

Preferably, the cable bridge completely traverses the opening 1d axially parallel or substantially parallel to the brake disk rotation axis or rotation axes.

The cable bridge 271 may be made of metal. It can also advantageously be formed simply as a stamping / curved part of a metal sheet. However, it may also be made of other materials.

The cable bridge 271 preferably includes a central bridge section 272. This bridge section 272 is here designed in a straight line. The bridge section extends parallel or substantially parallel to the brake disk rotation axis D in a state where it is installed.

The bridge section 272 preferably includes first and second fastening means 273, 274 on two opposite ends. These first and second fastening means 273 and 274 of the cable holder or cable bridges 271 and 271 are connected to a brake caliper 1 (Figure 21) or an element (Figure 22) fixed on the brake caliper 1, 271, 272, 274, 276, and 276, respectively, of the first and second corresponding fastening means 275, 276 of FIG.

The first and second fastening means 273 and 274 of the cable holder or cable bridge 271 and the corresponding first and second corresponding fastening means 275 and 276 of the brake caliper A second fixation may be formed on the other side of the first fixed or brake caliper 1 which has as little tolerance as possible on the other side of the opening 1d.

To this end, the first and second fastening means 273, 274 may be provided on the end opposite to the cable holder 271, or in the end (not shown), according to a variant And may be formed as a circular hole 273 and a longitudinal hole 274. The corresponding corresponding fastening means 275 and 276 may in this case be advantageously formed simply as screws 275 and 276 of the brake caliper 2 or as a pin or the like, For example, screwed to the bore of the brake caliper 1. The brake caliper 1 is fixed to the bore of the brake caliper 1, for example.

When one end of the hold down bar 250 fixed to the brake caliper 1 is fixed to the brake caliper 1 in the shape locking manner by the pin 255 (Figs. 1A, 9, 21) The pin 255 thus fixed on the brake caliper 1 can penetrate the bore 276 (preferably in the longitudinal hole for compensation of the tolerance). In this case, the longitudinal hole 276 can be displaced on the pin. The end of the hold down bar 250 with the bore 276 is in this case arranged like a flat washer between the head of the pin 255 and the contact surface of the brake caliper 1. This fixation variant is structurally simple and cost-effective, since a single fastening means (pin 255) is used in duplicate.

The cross-section of the bridge section 272 of the cable holder 271 is preferably U-shaped, according to a preferred embodiment. In this case, the U-shaped closed side is preferably directed towards the brake pads 100, 200 in order to implement a shield against heat radiated from the brake discs and the brake pads. The signal cable can then be inserted into the U-shaped bridge section 272 and secured therein. To this end, a tab 277 may be formed on the bridge section 272 such that after the signal cable 271 is inserted into the bridge section 272, the signal cable is partially or completely closed in a circumferential direction, Section 272, as shown in Fig.

The bridge section 272 can freely overlap the opening 1d. This means that the bridge section 272 is fixed on the brake caliper 1 only on, for example, only two ends as described above, and is preferably not fixed on the other elements of the disc brake.

However, the bridge section 272 may alternatively or alternatively have an opening 1d, which holds down only one of the two brake pads 100, 200 (either on its end or near the center in the bridge region 271) Down bar 250, but not across it completely.

To this end, it is advantageous that the other tab 278 of the bridge section 272 is fixed to the hold down bar 250 (see FIGS. 22A to 22C). This fixation can be done in a variety of ways. Thus, according to a preferred variant, a tab 278 may be arranged around the bridge 262 on the hold down bar 250 to surround such a bridge. In this case, a bridge 272, such as a finger element, is more advantageous when it axially protrudes from the end of the hold down bar 250 which radially holds down the brake pad assigned thereto. In this manner, it is possible in a simple manner that the hold down bar 250 and the bridge section 271 move in a manner constrained relative to each other, in particular that they can be pivoted. This relative movement may occur during braking. In this case, the tab 278 can form the corresponding fastening means 276 alone. Since the hold down bar 250 is a portion fixed to the brake caliper 1, the cable bridge 271 is again (indirectly) fixed on the brake caliper 1 in this manner.

However, the bridge section 272 may also be fixed on the hold down bar 250 in other manners, for example by at least one screw or rivet.

When the cable bridge 271 is fixed to the hold down bar 250, in particular to the bridge 262 of the hold down bar 250, by a frictional engagement locking method and / or a shape fitting locking method, As an example is shown, it is advantageous in this connection. The frictional engagement lock can be implemented by, for example, sidewardly mounting the cable bridge 272 to the hold down bar 250 in a clamping manner (not shown). In this case, it is possible to attach laterally (tangentially) in the circumferential direction to the hold down bar 250, particularly on the narrow side of the hold down bar 250.

In this manner, a cable bridge 272 is preferably formed which preferably performs cable guiding and thermal and mechanical shielding functions. In this case, the cable bridge 272 as described herein is on the one hand firmly connected to the working side on the brake caliper 1 (screw connection). On the reaction side, a kind of floating bearing is shown which compensates for the cable bridge to be fixed through the longitudinal hole on the bolt or pin 255 of the hold down bar. Thus, the cable bridge 272 can compensate for the caliper distortion well.

However, the fixation may also appear as a pad bearing bolt or pin as a fixed bearing and a fixation device on a caliper on the other side of the aperture 1d as a floating bearing.

The cable guide on cable bridge 272 is implemented as far as possible from the brake disc to keep the temperature load as low as possible. On the other hand, the cable guide is provided with a shadow of the axial tensile strut of the brake caliper 1 in order to be well protected from foreign matter (e.g., ice, contaminants, stones) As shown in Fig. This minimizes the reduction of the thickness of the cable guide.

In the following description of FIG. 23, terms such as up, down, left, right, front, rear, and the like refer to an exemplary representation of a brake carrier, brake pad, carrier horn, bridge, . This concept should not be construed as limiting, that is, through various work locations, such a relationship may be changed.

In FIG. 23, reference numeral 1001 denotes a brake carrier for a pneumatic or electromagnetically operable disc brake of a vehicle, in particular a commercial vehicle, in particular according to one or more of the schemes of FIGS.

The brake carrier 1001 has a connecting area 1002 which serves to fix, for example, on a vehicle shaft (not shown here) by screwing it with the shaft flange of the vehicle shaft of a commercial vehicle.

A pad shaft serving to receive and support at least one brake pad 1009 is molded on the upper portion of the connection area 1002. [

In this case, the brake carrier 1001 shown here includes two such pad shafts. Here, the brake carrier 1001 is configured to extend across both brake discs of the disc brake, and a pad shaft for accommodating the brake pads 1009 in each case is formed on both sides of the brake disc.

In this case, each of the pad shafts preferably has an inlet side carrier horn 1004, 1007, an outlet side carrier horn 1005, 1008 and an inlet side plate horn 1004, 1007 with respect to the running direction "forward of the vehicle" Is formed through bridges (1003, 1006) connecting outlet-side carrier horns (1005, 1008).

In this case, the carrier horns 1004 and 1005 and the bridge 1003 represent the working side. Correspondingly, on the reaction side of the brake carrier 1001, an inlet side carrier horn 1007, an outlet side carrier horn 1008 and a bridge 1006 are formed.

In a further explanation, the formation of the actuation side pad shaft is described in more detail.

In this case, the pad shaft on the reaction side is implemented in the same manner. However, it is also conceivable to form the reaction side pad shaft at least slightly different from the operation side pad shaft.

The area of the bridge 1003 adjacent to the carrier horns 1004 and 1005 forms bearing surfaces 1031 and 1032 that serve to radially support the brake pads 9, Side 1096 is supported on the bearing surfaces 1031 and 1032 in the inserted state. The bridge 1006 on the reaction side of the brake carrier 1001 also includes such bearing surfaces 1061,1062.

A pad retaining spring 1010 is preferably retained on the upper side of the brake pad 1009 opposite the lower side 1096. The pad retention spring 1010 is here secured, preferably on the retaining lug 1098, to the outer edge of the upper side of the pad carrier plate 1091 of the brake pad 1009.

The carrier horns 1004 and 1005 each include inner side surfaces 1041 and 1051 facing the pad shaft and at least the brake pad 1009 Of the side surfaces 1092 and 1093 of the pad carrier plate 1091 are supported with respect to the inner surface.

Guide contours 1044 and 1054 are disposed on opposite sides 1042 and 1052 of the brake discs of the carrier horns 1004 and 1005, respectively, and the guide contours are positioned on the brake pad 1009 from the side of the pad shaft into the insertion position. As shown in FIG. In this case, the insertion position means that the brake pad 1009 can be inserted into the pad shaft between the carrier horns 1004 and 1005 in the axial direction relative to the vehicle axis (not shown) or the rotational axis of the brake disc It indicates the position where it is.

These guide contours 1044 and 1054 are preferably formed as the material expansions of the carrier horns 1004 and 1005 as shown in Figures 24 through 27 by the side surfaces of the carrier horns 1004 and 1005, 1042, and 1052, respectively.

Through which radially guided along the sides 1047 and 1057 of the rail portion of the carrier horns 1004 and 1005 in the direction z of the axis of rotation of the brake disc, The pad carrier plate 1091, which is laterally offset shifted, abuts against the guide contours 1044, 1054 with the lower edge in the direction z when radial movement, It becomes possible to guide the pad 1009 to its central position until it is placed in the mounting area 1033. [

The mounting area 1033 defines an additional bearing surface of each bearing surface 1031,1032 of the area of the adjacent bridge 1003 on the carrier horns 1004,1005, 1009 are prevented from being displaced too far in the direction of the rotational axis of the brake disc on the pad shaft.

Instead of molding the guide contours 1044 and 1054 on the sides of the carrier horns 1004 and 1005, it is possible in principle to provide these guide contours 1044 and 1054 as separate, e.g., , 1054 may also be considered.

The working side surfaces 1042 and 1052 of the carrier horns 1004 and 1005 also include receptacle bores 1043 and 1053 that serve for the sliding bearing of a brake caliper that is not shown.

As also shown in FIGS. 1-5, the guide contours 1044 and 1054 of the carrier horns 1004 and 1005 of the pad shaft are formed to be narrower toward the bridge 1003.

Thus, the guide contours 1044 and 1054 include a straight line area that is positioned at two angles to each other, as best seen in Figures 23 to 25 in particular.

In this case, the first rectilinear region is arranged to have an angle with respect to the insertion direction z, and acts so that the brake pad 1009 is guided to a central position between the carrier horns 1004 and 1005.

The second linear region is aligned radially, that is, with respect to the insertion position z, so that the brake pad 1009 is positioned in the axial direction with respect to the rotational axis of the brake disc after reaching the mounting region 1033, , 1005 in the insertion direction (y).

In the variant of the brake carrier 1 shown in Figures 1-5, projections 1045 and 1055 are molded on the inner sides 1041 and 1051, respectively, of the carrier horns 1004 and 1005, Serves to fix the brake pad 1009 in a radial direction by a correspondingly formed pad carrier plate 1091 having a lateral recess 1094. [

Below the protrusions 1045 and 1055 of the carrier horns 1004 and 1005 are formed receptacles 1046 and 1056 for receiving respective projections 1095 of the pad carrier plate 1091, Contours 1044 and 1054 terminate at the lateral edges of the respective receptacles 1046 and 1056, respectively. In this case, the height h ₂ of the protrusion 1095 preferably corresponds to the height h ₁ of the receptacles 1046 and 1056 of the carrier horns 1004 and 1005, so that the brake pad is radially 1046 and 1056, respectively.

In alternative alternative embodiments of the brake carrier 2100 shown in Figs. 28 and 29, the guide contours 2144 and 2154 are implemented in the same manner as by the brake carrier 2100 previously described.

The substantial difference between the previously described brake carrier and this brake carrier 2100 is the inner surfaces 2141 and 2151 of the linear (flat) carrier horns 2140 and 2150, so that the brake carrier 2100 , Besides the direct introduction of the brake pads between the carrier horns 2140 and 2150, also lateral offsetting with respect to the brake pads is also possible in a simple manner, wherein the exact center alignment of the brake pads is also referred to herein as a guide As well as through the outlines 2144 and 2154 and through the mounting area 2131 on the bearing surfaces 2131 and 2132 of the bridge 2130.

The brake carrier 2100 is also implemented to span both brake discs (not shown) in the variant embodiment shown here, so that the carrier horns 2140 and 2150 and the bridge 2130 form the working side pad shaft Carrier horns 2170 and 2180 and bridge 2160 form a reaction side pad shaft.

Preferably, only the working side carrier horns 2140, 2150, 2140, 2150 are configured to have such guide contours 2144, 2154, 2144, 2154 to guide the brake pads from the side of the pad shaft to the insertion position .

While the reaction side carrier horns 2170, 2180 are preferably formed without such guide contours. Similarly, the bearing surfaces 2161, 2162, 2161 and 2162 of the reaction side bridges 2160 and 2160 are formed so that the width in the direction of the rotation axis of the brake disk is equal to the width of the carrier horns 2170, 2180, 2170 and 2180 Respectively.

The present invention is not limited to the above-described embodiments. The invention may be modified in various ways within the scope of the appended claims.
